During peak storms, these waterways appear powerful and strong as they transport large debris and carve new paths. However, they are fragile and rely upon all the contribung natural condions in a watershed for their health and longevity. In both rural and urban areas, a creek is an irreplaceable natural resource. Whether it ows year round or seasonally, your waterway provides a conduit of benets that sustains all life forms in its reach. People are also part of the natural, living system within every watershed. People are key factors in keeping the waterway and its corridors healthy. You and your creek-side neighbors share this responsibility. The purpose of this guide is to give rural and urban landowners a sense of their place in the many watersheds found in San Luis Obispo County, to promote praccal creek care informaon and to oer a host of resources to help with the maintenance and preservaon of creek-side property. Because most creeks in San Luis Obispo County ow on private property, landowners and local residents play a key role in protecng and improving the health of creeks. This stewardship guide will educate creek-side residents throughout the County on how to responsibly care for their prop- erty. It contains realisc guidelines for habitat enhancement and restoration projects, including permitting requirements, and a reference secon with sources for project assistance. View of the Nacimiento River from San Ardo 1 Resource Conservation Districts in San Luis Obispo County Resource Conservaon Districts (RCDs) are legal subdivisions of the State, formed under Division 9 of the Public Resources Code, to provide local leadership in the conservaon of our soil, water, and related natural resources. RCDs were originally developed in the 1930s as the local non-regulatory mechanism for delivery of conservaon pracces for farmers dealing with the Dust Bowl. They have grown considerably in size and scope, exisng currently in all y states. There are over 100 RCDs in California, two of which are located in San SLO COUNTY RCD SERVICES: Luis Obispo County: Upper Salinas-Las Tablas and Coastal San Luis. RCDs provide a broad variety of services to landowners in their respecve dis- Permit Coordinaon with Regulatory Agencies tricts through grants and cooperave agreements with other agencies. Agricultural Grading Permits By pursuing diverse funding sources, RCDs typically leverage their con- Irrigaon Evaluaons stuents tax dollars into hundreds of thousands more for on the ground Small Acreage Livestock Improvements projects in their districts. For every $1 contributed to an RCD, they can Agricultural Engineering return up to $21 in other funding sources.

A watershed consists of the land area that drains to a single body of water such as a river, creek, lake, wetland or estuary. Physical boundaries and topography, such as ridgelines, dene the movement of water and delineate the watershed. Water within a watershed follows the hydrologic cycle which begins when water falls to the earth in either liquid or solid form. The water is then captured by the soil and is either taken up by vegetaon, retained in the soil, or percolates through the soil. The water may enter into springs, creeks, rivers, lakes, groundwater basins or the sea for storage where it can then be returned to the atmosphere by evaporaon and start the cycle again. Modicaons within a water- shed, such as the creaon of impervious surfaces or extensive vegetaon removal, can interfere with the hydrologic cycle and have a detrimental eect on waterways. The watersheds in San Luis Obispo County have changed from their natural states due to modern selement. Oak forests were cleared for development and to create spa- cious open areas for farming and grazing. Rivers, creeks, and tributaries were con- ned by levees, dams, and ditches. Culverts and roads blocked sh passage to spawning habitats. As a result, steelhead trout and white bass are now listed as threatened spe- cies throughout the Countys creeks. Creeks, however, are resilient. As we learn to understand them beer, we are bet- ter able to care for them. Many eorts Hydrologic Cycle are underway to protect and restore the natural funcon and resources of the Countys major waterways. Resource Conservaon Districts, community watershed groups, local governments, and State and Federal agencies are working to reduce erosion and pollut- ants, improve sh passage and habitat, maintain healthy summer ows for perennial creeks, and establish nave riparian vegetaon. Climate Anyone who has listened to the weather report for San Luis Obispo County knows that it is home to a Mediter- ranean climate which oers a variety of microclimates. Travelling from the coast to inland areas, temperatures can drop by nearly 30°F in the winter months and can increase by the same margin in the summer months. Annual rainfall throughout the County diers just as drascally. The majority of rainfall occurs in the winter months between November and April. Northwestern areas of the County receive an average of 42 inches of annual precipitaon while eastern areas only receive about 10 inches. The variance in temperature and rainfall has a signicant impact on the watersheds of the County. The main inuence on a waterways ow is rainfall runo from its watershed. Some waterways in the arid regions of the County run dry in the summer months while others ow year round. The presence of both perennial and intermient waterways makes management of these resources closely linked to the climatology of the area and weather paerns. 3 Unique & Diverse Watersheds & Sub-Watersheds of San Luis Obispo County 1.

The Cholame Creek watershed has an arid Mediterranean climate with average precipitaon between 11 and 17 inches per year.

The headwaters are located in the La Panza range with the highest point at approximately 3600-feet. The confluence of San Juan Creek with the Estrella River occurs at Shandon. The dominant land use is agriculture. The San Juan Creek Valley is generally used most intensively for agriculture because of better soils and water availability. Irrigated production has increased during the last 10 years, particularly in vineyards and alfalfa. Dry farming and grazing operations encompass the rest of the agricultural uses. The riparian forest and a portion of the adjacent upland areas associated with the Estrella River and San Juan Creek in the vicinity of Shandon are important wildlife habitat, and serve as important corridors for wildlife movement. San Joaquin kit fox and Western burrowing owl occur in open grasslands. Another important wildlife movement corridor is located near the base of the hillside near the eastern edge of Shandon.

Plans are published by the U.S. Fish and Wildlife Service, and sometimes are prepared with the assistance of recovery teams, contractors, State agencies, and others. Objectives will be attained and any necessary funds made available subject to budgetary and other constraints affecting the parties involved, as well as the need to address other priorities. Recovery plans do not necessarily represent the views nor the official positions or approval of any individuals or agencies involved in the plan formulation, other than the U.S. Fish and Wildlife Service. They represent the official position of the U.S. Fish and Wildlife Service only after they have been signed by the Director, Regional Director, or Manager as approved.

A portion of the watershed is located in Monterey County with a majority of the acreage located within SLO County. The Estrella and some of its tributaries carry perennial underground flows that form a tributary of the Salinas River. The Estrella River forms from the confluence of San Juan Creek and Cholame Creek near Shandon, in the foothills of the Coast Ranges. The confluence of the Salinas and Estrella Rivers occurs in Northern San Luis Obispo County, within Photo: Althouse and Meade the town of San Miguel. The highest elevation in the watershed is approximately 2,854 feet, and the lowest elevation is around 607 feet. Vineyards slightly predominate over oak woodlands and grassland communities. Tree species such as blue oak, and valley oak dominate the oak woodland, while western sycamore, Fremont’s cottonwood, and willows are found in the riparian woodlands along the Estrella River. Agriculture is the dominant use. The Estrella River Valley is generally used most intensively for agriculture because of better soils and water availability. Irrigated production has increased during the last 10 years, particularly in vineyards and alfalfa.
